Rear Hole Development
With her restraints released, Heo Seong-ah was grabbed by the Manager and led out of the oral pussy training room. Crawling on all fours with an arm-thick dildo crammed in her mouth had been torture far harder to endure than she'd imagined. Letting her walk on two legs was the Manager's final act of consideration for his livestock.
"Urk..."
Even on two legs, she wasn't truly free. A blindfold blocked her vision, and the leash was gripped tightly in the Manager's hand. To prevent any sudden outbursts, her hands were bound securely behind her back.
"Guhk..!"
The dildo invading her mouth reached all the way to her stomach, crushing her insides with pain at every step. She desperately wanted to spit it out, but the leather mask was fastened tightly behind her neck—impossible to remove on her own.
"Eurk..."
Her throat was in bad shape, but worse was her stomach, sloshing full of semen with each footfall. Regardless of her will, her gut churned violently, spreading horrific abdominal cramps. Is this what pregnancy feels like? Such a naive thought crossed her mind just as they arrived at their destination.
"B62, what training did I say comes after oral pussy training? If you get it right, I'll specially shorten the session."
"Urk..."
Heo Seong-ah knew the answer. He'd said anal training came next. Her mind wasn't broken enough to forget that. But she couldn't speak—the dildo filled her mouth completely.
"No answer? Shall I assume you don't know?"
"Guuuhk..!"
The Manager knew full well she couldn't speak, yet he yanked her leash taut, demanding a response.
"B62, if you don't answer, I'll deem you as ignoring my words and maintaining a rebellious attitude, extending the training to maximum length."
He planned this from the start... He framed every action as Heo Seong-ah's own fault. By constantly prodding her psyche like this, soon enough she'd accept any torment as her own doing and adopt unwavering obedience. Classic gaslighting training. Psychological torture she saw through but couldn't escape.
"Ahurk..!"
Desperate to do something, Heo Seong-ah answered with action instead of words. She turned her back to the Manager and wiggled her hips side to side.
The awkward motion was so ridiculous that the Manager burst into involuntary laughter.
"Puhahaha!! What the hell is that, B62? I don't remember teaching comedy routines."
"Urk..."
"Fine. That was a good physical gag, so I'll let it slide this once."
For fun, the Manager spread his palm wide and slammed it down hard on her ass.
Paang—
"Guhk!"
The impact sent Heo Seong-ah stumbling forward a couple steps; she barely caught herself from falling. But... wait...? Why was there no pain?
"Ah, right—I forgot to explain this suit's function."
No need to elaborate, but since she'd wear it throughout training, informing her wasn't a bad idea.
"B62, listen closely—I'll only say this once."
"Urk..."
"This latex suit is the pinnacle of scientific achievement, crafted with utmost care by the processing lab researchers. It goes beyond mere restraint, completely separating pleasure and pain sensations."
Hard to grasp from words alone... but it was true her hypersensitive body—ruined for normal life—had calmed down thanks to the suit. And true that the spanking hadn't hurt.
"The catch is the side effect: during wear, all stimuli to those areas accumulate. No matter how brilliant the PhDs, some scientific limits can't be overcome."
In truth, solutions existed once the side effect was discovered... but leaving it in made things more fun, so the latex suit was finalized as-is.
"Not getting it? Your body feels nothing now, B62, but pleasure keeps piling up inside. The moment you take it off, it all hits at once."
"Eugk..."
"And that spanking pain? It'll crash in suddenly when the suit comes off too. One hit's fine, but ten... a hundred... a thousand... If it all bursts forth accumulated, you might go into shock and die."
Saying it lightly as if it were someone else's fate, the Manager smirked, pulling a telescoping baton from his inner pocket and extending it.
"While we're on the topic..."
"Gurk?!"
He yanked the leash hard, toppling her body. As she collapsed limply to the floor, he pinned her back with his foot and swung the baton down on her ass.
Paang, paang, paang— Each full-force strike made the latex-clad flesh jiggle. It should hurt like hell, but Heo Seong-ah felt nothing, only letting out uncomfortable groans as her body squirmed.
The Manager swung until his arm ached, then stowed the baton.
"Haa, huu... Roughly thirty hits. Still not feeling it?"
"Uuuurk..."
"Can't wait for later. Wonder what pathetic face you'll make screaming..."
Looking forward to that day, the Manager tugged the leash again, hauling her upright.
"Here's the deal: from now on, whenever you're not diligent in training, I'll punish you with beatings. Any spot I choose. Got it?"
"Ugh..."
She couldn't answer. Not even nod.
"I'll take that as agreement... Time to enter the training room."
"Urk..."
Whiiiing— With the door sliding open, Heo Seong-ah followed the Manager's footsteps into the Anal Training Room.
Like everywhere else, the narrow five-pyeong room was lined with shelves of training tools. The difference? These were exclusively for tormenting... for ruining the anus.
"B62, sit here and wait."
Still bound behind her back, she was led somewhere and planted on a hard wooden chair. No special restraints, yet she sat obediently, not rising—a picture of good behavior.
Humming to himself, the Manager prepared the tools: from cute small-scale fake cocks... to grotesquely shaped "special tools" that'd bring tears at first sight. Blind, Heo Seong-ah trembled, imagining what awaited.
"All set."
His voice made her shoulders flinch in tension.
"No need to tense up. It won't even hurt."
The Manager fetched metal restraints and set them on the floor. Hooks on top and bottom connected via chains for binding.
"B62, get down here on your belly."
"Euuuk..."
Guiding the blind girl himself, he gripped her bound arms, positioning her at the center.
"Down now."
With a kind voice... gentle hands... he pressed her waist lightly, forcing her prone. He secured her ankles first, then wrists. As always, she ended up in all-fours beast pose.
Familiar enough that it didn't feel uncomfortable. The chains were even loose enough for some arm and leg movement—no real sense of restraint.
"B62, do you know this fact?"
Slipping on latex gloves, the Manager stirred aphrodisiac-laced gel with a rod as he spoke.
"People say men feel more anal pleasure than women because of the prostate—but that's wrong."
"Uuuuh..."
"Women have less aversion to insertion. With proper, gradual development over time, it can become an organ delivering pleasure stronger than the pussy."
Not baseless talk. Repeated aphrodisiac training would warp her body into one that craved it perversely, whether she wanted or not.
"They say excretion desire outstrips even sexual lust. With your prime body, B62, a little ass play and you'll be drooling fluids, cumming nonstop."
"Uuu..."
Heo Seong-ah felt shame, somehow believing it could happen.
"All prepped."
Time for serious anal development. The Manager took a strange needle, pricking the latex suit's crotch. Like slicing paper, he lightly sliced open the ass-covering section.
A sudden cool sensation between her legs made her squirm in confusion.
"Huuuwaa..."
He adjusted the hole precisely to expose only the anus—ignoring everywhere else. A massive dildo-plugged hole peeked out defiantly.
"Let's begin."
"Huuu..."
Now, truly... there was no escape.
